I have used heads with similar sized blades and have never attributed any problems to the blade size. If the head hits in the " pan," the deer is in as much trouble as if hit by a larger blade. I do not suppose you ever heard of the " Missile Spike?"

How about the original " Wasp Broadfield" It was a 125 grain, three-bladed head with an aluminum ferrule. The blades were modified " Schick" injector blades with a 1-1/16 inch cutting diameter. Most of the blade was buried in the ferrule, only a small portion created the cut. That head brought down many deer. I knocked down a 240 lb, 8-point buck with a " Broadfield," shot from a 51 lb. recurve.

What is the difference between 1-1/16th and 1-1/8th (a common size)? 1/16th. What is the difference between 1-1/16th and 1-3/16th? 1/8th. I will give up 1/16" or 1/8" for better aerodynamics and flight.

What drew my attention to the Rocket Ultimate Steel, were the price I paid and the design. Steel ferrule, heavy gauge stainless steel blades, and a short ferrule. As soon as the ferrule punches through, the blades are very close behind and cutting. Almost a quasi-cut-on-contact blade, but with a " Trocar" tipped ferrule and replaceable blades.

If everything goes as planned this season, I will know if the field performance of the head coincides with what I believe the head can do.
